Concurrent or sequential development of medial meniscal and subchondral cystic lesions within the medial femorotibial joint in horses (1996-2006).
Abstract: Summary Reasons for performing study: Medial meniscal injuries and subchondral cystic lesions (SCL) are known to occur independently within the medial femorotibial (MFT) joint in horses. However, there are no reports of a potential clinical relationship between these 2 types of lesions. Objective: To: 1) document the concurrent presence or sequential development of medial meniscal and SCL of the medial femoral condyle within the MFT joint; and 2) determine the prognosis with both types of lesions. Methods: Retrospective case series of horses with both a medial meniscal and SCL of the medial femoral condyle identified concurrently or sequentially by radiography, arthroscopy or post mortem examination. Case records and radiographs were reviewed, and a telephone survey of referring veterinarians, owners and trainers was conducted. Results: Twenty-one horses (9.1% of all horses undergoing MFT joint arthroscopy) were identified to have both a medial meniscal injury and SCL of the medial femoral condyle. Thirteen horses had both abnormalities identified concurrently, 6 developed a meniscal lesion subsequent to SCL debridement, and 2 developed a SCL subsequent to a medial meniscal injury. Only 4/19 horses were classified as successful and returned to their intended use. The severity of the meniscal injury was significantly associated with the severity of lameness but not with outcome. Conclusions: A low percentage of horses may develop both a meniscal injury and SCL of the medial femoral condyle within the MFT joint and have a poor prognosis. Conclusions: Trauma to the MFT joint may lead to both meniscal and subchondral bone damage of the medial femoral condyle that may be recognised concurrently or sequentially.

The research article investigates the possible relationship between medial meniscal injuries and subchondral cystic lesions (SCL) in horses’ medial femorotibial (MFT) joint and their prognosis.
Objective and Methodology
The two main goals of this study were to:
- Document the simultaneous presence or sequential development of medial meniscal injuries and SCL in the medial femoral condyle within the MFT joint of the horse.
- Understand the prognosis when both these types of lesions co-exist.
The researchers took a retrospective approach where they examined case records, radiographs of horses identified with both medial meniscal injuries and SCL, and conducted interviews of relevant stakeholders. The method used for identifying these injuries was radiography, arthroscopy or post-mortem examination.
Results
The results revealed that of all the horses undergoing MFT joint arthroscopy, 9.1% or 21 horses, exhibited both a medial meniscal injury and SCL of the medial femoral condyle.
The findings included three scenarios:
- Thirteen horses were found with both abnormalities at the same time.
- In six cases, a meniscal lesion developed after debridement of an SCL.
- Two horses developed an SCL after a medial meniscal injury.
The results also indicated a poor prognosis as only 4 out of 19 horses could return to their intended use. It was also found that the lameness in the horses correlated with the severity of the meniscal injury but did not necessarily determine the outcome.
Conclusions
The conclusion of the study suggests that a small percentage of horses may simultaneously develop a meniscal injury and SCL of the medial femoral condyle within the MFT joint and display a poor prognosis. The findings indicate that trauma to the MFT joint may result in both meniscal and subchondral bone damage of the medial femoral condyle that can occur concurrently or sequentially.
